Liquid nitrogen cryopreservation of Bracoccidioides brasiliensis in Fava's Netto medium
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2020)
Mathematical prediction of freezing times of bovine semen straws placed in static vapor over liquid nitrogen
(Academic Press Inc Elsevier Science, 2013-02)
A widespread practice in cryopreservation is to freeze spermatozoa by suspending the straws in stagnant nitrogen vapor over liquid nitrogen (N2V/LN2) for variable periods of time before plunging into liquid nitrogen (-196 ...
Cooling balloons with liquid nitrogen
(American Association of Physics Teachers, 2010-12)
We present an undergraduate level experiment in which the radius of a rubber balloon is measured as it is cooled with liquid nitrogen. For balloons filled with simple gases that condense at liquid nitrogen temperatures, ...
Partition coefficients of organic compounds between water and imidazolium-, pyridinium-, and phosphonium-based ionic liquids
(Springer Heidelberg, 2014-10)
The partition coefficients, P IL/w, of several compounds, some of them of biological and pharmacological interest, between water and room-temperature ionic liquids based on the imidazolium, pyridinium, and phosphonium ...
Measurement of nitrogen dioxide and nitrous acid using gas-permeable liquid core waveguides
(2001-03-15)
Nitrogen dioxide is an important atmospheric contaminant, classified as a criteria pollutant in the United States. It can be sensitively determined by the simple colorimetric Griess-Saltzmann method. This can constitute ...
Determination of Heat Transfer Coefficients for French Plastic Semen Straw Suspended in Static Nitrogen Vapor Over Liquid Nitrogen
(Cryo Letters, 2015-12)
BACKGROUND: The use of mathematical models describing heat transfer during the freezing process is useful for the improvement of cryopreservation protocols. A widespread practice for cryopreservation of spermatozoa of ...
Effect of ammonia load on efficiency of nitrogen removal in an SBBR with liquid-phase circulation
(Brazilian Society of Chemical Engineering, 2008)
The removal of biological nitrogen from a synthetic wastewater with different ammonium nitrogen concentrations (50 and 100 mgN-NH4+/L) by a nitrification and denitrification process using a sequencing batch biofilm reactor ...
Solvatochromic parameters of imidazolium-, hydroxyammonium-, pyridinium- and phosphonium-based room temperature ionic liquids
(Elsevier Science, 2016-01)
Solvatochromic solvent parameters of different room temperature ionic liquids based on the imidazolium, hydroxyammonium, pyridinium and phosphonium cations, namely 1-butyl-3-methyl imidazolium hexafluorophosphate, ...
